The CN7400 Series temperature/process FM-approved limit controllers set a new standard in 1/16 DIN limit controls. They have universal inputs (10 thermocouple and 4 RTD types, voltage, and current). Standard features include remote reset capability. Outputs include normally open (form 'A') and normally closed (form 'B') relays. Form 'A' and form 'B' relays can be set up for each setpoint output and logically linked to emulate a form 'C' output.
